You mean, you need somebody else to tell you if you're sold "view" today, it does not include guarantee nobody will ever build anything on the land between you and the "view" ever, just because otherwise you'd feel bad? You can not figure this out just from knowing you only own property rights on the small piece of land and not on anything else, and did not buy any "view" rights? Maybe if you can not figure this out, buying expensive property is not the best way to go for you, at least without consulting somebody knowledgeable in these matters. You can not expect everybody behaves in your best interest, and they certainly do not owe that to you. If you don't own the rights and the land, there's zero guarantee the view will be there tomorrow.
